摘要： The pipeline pig disclosed includes a cup-shaped cleaning element having a spherically shaped outer surface with a diameter equal to or greater than the inside diameter of the pipeline for engaging a pipeline inner wall even as the pig passes through curved sections of the pipeline. The cleaning element has a plurality of grooves in its outer surface that provide a plurality of scraping edges to scrape rust, scale, and other substances from the inner wall of the pipeline.

摘要： A pipe pig is reciprocated through a section of a pipe having deposits of scale. In the case of very hard deposits, each pass through the contaminated sections removes a thin layer each time. The location of the coated section can be located by first running the pig through the pipe. The hydraulic pressure is monitored using pen recorders. At each bend in the pipe, a sharp pressure increase will be recorded. The location of the bends can be determined from a drawing of the pipe installation. When the pig encounters scale, there will be a pressure increase that corresponds to the degree of resistance met by the pig resulting from the scale. Greater pressure means greater scale build up. By running the pig through the pipe, a profile of the scale may be created. The location of the scale can be correlated to the known location of the bends. The scale itself can be flushed out with the hydraulic propellant and analyzed. The pin height and hardness can then be selected for the particular scale encountered. The pig may be run backwards and forwards primarily through the contaminated section. After several passes, the pig can be removed from the pipe, the pins replaced or moved radially outward by placing washers between at least some of the pins and the pig body and the pig returned to the pipe.

摘要翻译： 管猪通过具有鳞片沉积物的管道的一部分往复运动。 在非常硬的沉积物的情况下，每次通过污染的部分每次去除薄层。 涂覆部分的位置可以通过首先通过管道运行猪来定位。 使用笔式录像机监测液压。 在管道的每个弯曲处，将记录一个明显的压力增加。 弯曲的位置可以从管道安装图中确定。 当猪遇到规模时，会有一个压力增加，相当于由秤产生的猪遇到的阻力程度。 更大的压力意味着更大规模的建立。 通过管道运行猪，可以创建秤的轮廓。 刻度的位置可以与弯曲的已知位置相关联。 水垢推进剂可以将其自身冲洗出来并进行分析。 然后可以针对遇到的特定尺寸选择销的高度和硬度。 猪可能主要通过污染部分向后和向后运行。 经过几次之后，可以从管中取出猪，通过在至少一些销和猪体之间放置垫圈将排针更换或径向向外移动，并将猪返回管道。

摘要： A pipeline pig has hollow flared ends and a central portion of smaller radial dimension than adjacent parts of the pig. Detachable appendages extend radially outward from the pig in circumferential rows. At least one row of appendages is in the central portion and the appendages extend radially outward less than the other rows of appendages. The appendages are threaded into sleeves having anchored bases. The row of appendages that extends radially outward by a smaller amount than the other appendages is subjected to reduced wear, but when the pig encounters resistance, the central part of the pig extends outward bringing the appendages into contact with the interior of the pipeline.

摘要： A method of cleaning a nitric acid absorption column cooling coil having an access port and an exit port comprising the steps of closing the access port, inserting a pig in an operative position within a sealable cavity of a launching assembly that is operatively attached to the access port to allow the pig to enter the coil, pressurizing the launching assembly with a fluid to a pre-determined level, opening the access port while maintaining pressure against the pig during its passage through the coil by a fluid pump sufficient to force the pig into and through the coil, and capturing the pig after it passes through the exit port.

摘要： An improved process for cleaning the interior of a conduit having a series of straight sections and bends. The process includes passing a transit line having a multiplicity of flow divertors positioned at intervals along the length thereof through said conduit. By injecting a propelling gas stream having cleaning particles entrained therein, the multiplicity of flow divertors serve to enhance the in-situ cleaning action of the particles while the propelling gas stream serves to activate the flow divertors and cause the transit line to move along the straight sections and around the bends of the conduit.
